[0007] As a preferred embodiment of the utility model of a foamed rubber bracket with good heat resistance, the flame retardant layer is a flame retardant film or a flame retardant fireproof coating.

[0008] As a preferred embodiment of the utility model of a foamed rubber bracket with good heat resistance, the position and size of the positioning column are matched with the position and size of the insertion groove.

[0009] As a preferred embodiment of the utility model of a foamed rubber bracket with good heat resistance, the position and size of the positioning block are matched with the position and size of the card slot.

[0010] As a preferred foam rubber bracket with good heat resistance of the utility model, the positioning column and the insertion groove are connected by a snap-fit ​​connection between the snap-fit ​​groove and the positioning block.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. The utility model can protect the bracket in the flame retardant layer by covering the entire surface of the formed bracket, thereby achieving heat resistance of the bracket;

[0013] 2. The utility model can be conveniently used for supporting and packaging tubular objects by dividing the entire foam support into two independent first supports and second supports and by making the two independent first supports and second supports detachable.
